Well I got mine, after a little diffuculty with my post office, but that is another story...
First thing, it is light and it is shiny
Mine does work, so no problems with the top like Col. had with his. I also left the white gasket in mine. I could understand wanting to take it off upon seeing it initially. In fact if modistru hadn't done that and posted here, I may have done exactly the same.
All the threading has noalox of some sort on it. I cleaned them all, but didn't put any fresh noalox on it. It is noticeable without it, making it a little more difficult to thread. Will do that in a bit... and use something else? on the Juice Dispenser and noalaox on the other threads...
So I got a multimeter out and started trying to set the voltage to a usable level. That initially didn't go so well, in fact I blew my current favorite LR510 atomizer (my last LR

) But I had some new 510 atties in 2Ω. The learning curve is somewhat difficult IMO wrt setting the voltage. I practiced it a bunch and finally got it to 4vdc vice the 6.72v it was intially set at. Oh, BTW, I am using two 18350 batts (from the ScrewDriver MkII). All said and done, I put an atomizer on and dripped and all was good. So I put the tank on. Initially, not a good deal, I got dry hits right away, so I dripped some... I believe with that little hole dripping into the lower part where the atomizer connects is slow to move the juice...
I am a little hesitant to pull the JD off, as suspect the lower area will be full of juice? I dunno// OK pulling it now... it is not full of liquid? there is a slight liquid pooling around the base of the JD only. I tried hitting it without firing to see if I could increase the amount of liquid in the collector... Just a little bit now... hmm this is with Dekang RY4, so not any VG thick stuff. The JD is an interesting design. I bet that little hole took a while for Casear to figure out, and it is defintely juice viscosity dependant. Decided to prime it by putting some juice in the collector, then adding the JD onto it. Now it aint starving, but time will tell. Used that up and back to dry hits... Loosened the JD top... oh that allowed liquid down to the collector!!! Now I am flooding! LOL. OK gotta figure this part out so it will work OK. Another learning curve.
Overall, fit and finish is nice. Not sure what kind of aluminum is being used, so time will tell as to pitting etc, but I believe C. has had time to determine if it will pit or not and he mentions some sort of special anodizing. The new LV2 is so light, it's crazy! With the JD and a drip tip, it actually is still shorter then a ProVari with the 18490 batts. The new collector will make for spill free dripping and keep liquid from dripping down to the touch sensor, which was a slight inconvenience with the LV1. The on/off is nice, no more firing when I don't want it to. The voltage settings are very variable, especially with 2x18350 or 16340 batts in there. Havent tried with an 18650 yet. I think it is mandatory to have a multimeter to check the voltage intially, but once you know basically where you are set at and how to change the settings, you are OK. There is a learning curve though IMO.
BTW, check your spring in the tube! mine was off cantor and it is just sitting loose down in the tube.
So everything on my part is positive, weight, fit, finish, turn on/off, auto turnoff, variable voltage, & size. Only two issues are learning how to set the voltages (I don't have a connector setup yet to try the pc hookup, plus will have to dig out a pc - Mac guy here) and getting the JD to work as I know it should. I got the voltage, just trying to learn the JD now. Otherwise, a very,very nice Precious.
PS: Looks like by the time I got done writing this, talking on my cell, and playing with my LV2, the JD is working OK now. Plus that new atty is breaking in and I have a nice RY4 vape.
